Hierarchical Routing Method Oriented to Cross-Boundary Service Network

3. The hierarchical routing method oriented to a cross-boundary service network according to claim 2, wherein the step (2-2) comprises: when the user calls the reference services, first forwarding, by a service switch, a request of the user to the service router that the reference services belong to, and calling, by the service router, the corresponding services according to the routing strategy, wherein the routing strategy is a performance strategy that focuses on an overall performance load of a reference service network or a fastest strategy that focuses on a return speed of the services called by the user.

5. The hierarchical routing method oriented to a cross-boundary service network according to claim 4, wherein the fastest strategy comprises: after the service router receives the request of the user for the reference services, searching for all candidate reference services associated with the reference services and the mapping configuration file of the reference services, converting a parameter format according to the configuration file, simultaneously initiating call requests for all the candidate reference services, and returning a fastest result according to service response times.
